It doesn't just end with AI, but it seems the most blatant. At a bare minimum, he could assign someone to fulfill that vision for AI. Google has their own chips which they scale. Apple doesn't need to rebuild ChatGPT, but they could very much do what Microsoft does with Phi and provide Apple Silicon trained and optimized base models for all their users. It seems they are already doing something for XCode and Swift, but they're just barely scratching the surface.

I remember when the iPhone X became a thing, it was because consumers were extremely underwhelmed by Apple at the time. It's like they kicked it up less than a notch sadly.

If Tim Cook decided to be a little more of a visionary, I would say keep him. I would at least prefer he would delegate someone to do the visionary work, he will eventually need a successor.
